Most people buy one pair of sunglasses and use it for almost every situation. However, I believe that one pair of sunglasses is not enough as different lens colours are used in different conditions. Today, most of the major sunglass brands comes with lens switching technology and so sunglasses from those brands would your best buy as you would be able to change your lenses depending on the different environmental conditions.
Amber/ Yellow
Amber or yellow colors are intended for use in flat to hazy light conditions and offer high contrast necessary in high-speed and/or high altitude sports such as skiing or mountaineering by filtering out blue light which makes focusing difficult.
Pink
Vermilion (pink) actually helps to absorb light in foggy or grey conditions increasing contrast and depth perception, a must for high-speed sports in the winter.
Brown
Brown lenses offer the true-color perception characteristics of a grey or smoke lens, but also retains some of the blue-light removing / contrast increasing characteristics of a light amber lens.
Clear
Clear...why? Because if you're adventuring at night, it's the only lens color that will allow your eyes to see anything at all.
Grey
Grey or smoke colored lenses are best suited for driving or general use when depth perception is not as important as true color perception.
Blue
Blue and purple lenses are not recommended for any use other than fashionable as the color actually serves to increase the contrast-destroying characteristics of blue light.
Therefore, it's important that you recognize the conditions that you usually face and purchase 1 or 2 lenses to suit those conditions. Afterall, you want to maximise your sunglasses right?
